' This invention relates to printing presses, the chief object being toprovide improved means'for enabling the leading end of the web from anew or reserve paper supply roll to be joined to the active web of theexhausting paper supply roll without the 1 use of separate or additionalpressure rollers such as have hitherto been proposed for effecting thejoining of the two webs.

According to this invention means are provided for effecting contactbetween the new or reserve paper supply roll and the exhausting papersupply roll to cause the two paper webs to be pressed together betweenthesaid rolls so that by means of ad-- hesive previously applied say tothe reserve web, the latter can be joined or united to the active weband drawn'by the latter into the press, whereupon the active web can becut or severed from its reel or core to enable the supply to be drawnfrom the new or reserve roll; Each of the said'supply rolls may becarried on an angularly movable support 'such as a pair of angularlymovable members or arms mounted on a shaft or the like and either pairof the said membersior arms as aforesaid. The supply rolls are rotatablysupported by the said arms in any appropriate manner'and inoneconstruction each pair of the supporting arms may carry rotatablespindles having bungs or the like on their inner ends for engaging withthe ends of the reel or core within the paper supply roll to support thelatter. One (or both) of the bung spindles of each pair may be axiallymovable for enabling itto be moved into and out of engagement with thesaid reel or core. Angular movement may be imparted to either pair ofthe supporting arms by means of worm gearing which may be operated byhand or otherwise and in one example a worm wheel sector is mounted oneach of the shafts carrying the said supporting arms and is adapted tobe engaged by a worm on an operating spindle. The operating spindlespertaining to the two sets of worm gearing may be so disposed thateither can be engaged by a common operating device according towhichever of the two spindles is to be actuated. For the purposeofcontrolling the speed of rotation of each paper supply roll, brakingmeans may be associated with the aforesaid bung spindles which means maycomprise a friction band or gripping device around a part on or of onespindle of each pair'and adapted to be actuated by hand or by automaticmeans which lattermay operate according to the tension on the web as thelatter travels from either supply roll into the press.

In order that the said invention may be clearly understood and readilycarried into seen from one side of a printing press. can be moved forexample by partially ro- Figure 2 is a transverse view showing one ofthe paper supply rolls in its supporting arms and the actuatingmechanism for movin the said arms.

Figures 7 and 8 are respectively a side or a pair of angularly movablearms 3 secured on a transverse shaft 4 rotatably mounted in the sideframes or members 5 of the printing press. In the example shown, each ofthe 5 supportingarms3 receives at its upper end a short spindle 6,thesaid spindlesof each pair of arms 3 being in alignment and providedattheir inner ends with bungs 7 that are adapt- "ed to be fitted in theends of the reel or core 8 on which'the paper web is mounted to form thesupply roll. The said bung spindles 6 may be splined in sleeves orbushes 9 rotatably mounted in roller orother bearings 10 in the upperends of the said arms. The spindle in one of the aforesaid arms is heldagainst axial anovement and it is provided with awthrust .bearing 11 butthe other spindle is adapted :to be axiallynioved within its sleeve 9 sothat the bung 7 on the inner end thereof can be moved into engagementwith one end of the reel or core when the paper supply roll 18 111positionawith the other end of its reel or core engaged by-the bung onthe spindle having thesaidthrust bearing 11. In the example .25 shownthe outer end of the axially movable spindle is provided with a groovedcollar 12 withwhich engage pins 13 on a leverl l whose lower end isloosely connected to the supporting arm 3 byalink 15 whilst its upperend carries a swivel sleeve 16 .or the likein 1 moved outwardlyforwithdrawing the said bung fromthe reel or core; On the transverse shaft4 pertaining to each pair of supporting arms 3 is keyed or otherwisesecured aworm wheel sector 20, which is engaged by a worm 21 mounted ona spindle 22 in suitable bearings 23 in a fixed part be secured to theframe 5, the said worm spindles 22 pertaining to the two shafts l, beingin co-axial. alignment. The inner ends of the said spindles 22 areprovided with bevel pinions 24 and located between these pinions is abevel gear wheel 25 which is carried on a lever-26 pivoted at a positionbetween its ends to the fixedframe 5a the upper end of the said leverbeing adapted to be secured to the fixedframe by means of a detachablepin 26a in eitherof two positions. :VVhen the pin 26a is removed, theaforesaid lever 26 can-be moved to place the bevel gear wheel 25 intoengagement with either of the aforesaid bevel pinions 24 and when it isso --engaged it may be locked in engagement by lnserting the pin 26ainthe end of the lever 26 into a hole in the fixed frame 5a thussecuring the lever to the said frame as aforesaid. The bevel gearwheel25 mayzthen be rotating the aforesaid worm- 21 and impartmg angularmovement to .the worm sector 20,

spindlesfi in the supporting arms 3. After.

rotated by hand or otherwise and in the example shown its spindle'orshaft 27 is adapted to receive a detachable handle 28 so that it can berotated by hand for the purpose of the shaft 1 and the supporting arms3. 'During the supply of the web into the press from the active-roll 1-which-'initiallyis ofthe size shown in dotted lines 1min Figure-1 andbecomesreduced to the size shown at 1 in full 'lines'when approachingexhaustion the new or reservepaper supply roll may be wheeled into thepress on a truck or the likeinto a position in which it can be disposedor rolled between the'arms 3 that are to support it.

The lever26carry- J05 ingthe aforesaid bevelgear wheel 25 may now be moved toplace the latter in engage- .ment with-the bevel pinion" 2450f the wormgearing pertaining to the arms 3 carrying the active and exhausting roll1 andby rotating the aforesaid han'dle 28 the bevel gearing and the wormgearing is operated to move the suportin armswcarr in the active and ex-P z) 7 .hausting roll 1 so asto press this roll whilst rotatingagainstthe' aforesaid new or reserve roll which has been placed in theoperative position as aforesaid, so that the active web becomes unitedto-the reserve webrby the adhesive in "thelatter. The'active and'exhausting -supply roll may bear a'gainstthe other supply roll withresilient I or yielding pressur'e'to allow: for any unevenness and forthis purpose each worm21 may be so mounted on its operating spindle 22that itcan be n1ovedagainstthe action of a spring 2 9 when eitherrollisbeingpressed againstthe other but it can be-locked against such movement.by means of a pivotedslip co1lan30 that can be placed on theoperatingspindle to engage with a shoulder 31 thereon and thusretain thespindle against the endwise movement as is desirable for example whenraising the supply roll into the operative position. After the web fromthe reserve roll has been united to the active and exhausting web and isbeing drawn into the press and after the active web has been cut orsevered from its reel or core, the reserve roll becomes the active rolland after removing the reel or core of the exhausted roll from thesupporting arms 3 a new or reserve roll can be placed between these armsso as to be'secured thereto by the bungs-as aforesaid ready for the nextweb joining operation.

Forthe purpose of side lay adjustment each transverse shaft 4 carryingthe said supporting arms 3 for the supply roll may be threaded at oneend onto a rod 32 (or into a sleeve or bush) which is rotatably mountedin a fixed bar 33 and provided with a hand wheel 34 that can be rotatedto impart endwise move ment to the said shaft 4 and thus adjust thelateral position of the supporting arms as required.

Oneof the two bung spindles pertaining to each supply roll may beprovided with a brake for controlling the speed of rotation of thesupply roll as the web is drawn therefrom into the press and the brakemay comprise a split friction ring 35 or the like whichis locatedbetween the aforesaid roller bearings 10 around an enlarged part of thesleeve or bush 9 containing the bung spindle 6 and is adapted to becontrolled or regulated by a hand screw 36 (seeFigures 4 and 6).

The automatic braking mechanism shown in Figures 7 and 8 is located atone side of the press and is operated according to the tension on theactive web as it passes into the press from whichever of the two supplyrolls is at thattime serving as the active roll. The web from eithersupply roll passes around a spring influenced roller 37 and also aroundother rollers 38 and 39 as shown in Figure 7. The roller 38 is slidablymounted in a guide 40 and is connected by a link 41 to one end of thebell crank lever 42 whose other end is connected to a link 43 thatextends clownwardly and is pivotally attached to a lever 44 on a shaft45 carrying a pulley or wheel 46 around or to which two cables 47, 47are secured. The bell crank lever 42 is carried on shaft 42?) on whichshaft is rotatably mounted a worm wheel 55 that is engaged by a worm 56and is connected to a torsion spring 42a (see Figure 8) located aroundshaft 42?) so that movement of the roller 38 in its guide 40 due to thetension on the web is effected against the torsional action of thisspring. Each of these cables passes around a jockey pulley 48 on an arm49 angularly movable on the aforesaid shaft 45 whence it passes around apulley 50 on the transverse shaft 4 having the supporting arms 3 thatcarry the paper supply roll. The outer extremity of each cable isconnected to a bell crank lever 51 that is attached to a brake band52-surrounding the sleeve 9 in which the bung spindle 6 is splin-ed asaforesaid. -The said released by movement of the bellcrank lever 51 dueto the operation the aforesaid link and lever mechanism 41, 42 and 43according to the tension on the web passing into the press.

brake band52 is adapted to be contracted or 73 The outer end of each ofthe arms 49 is slotted- F5 to provide a sliding connection for one endof a link 53wh0s-e other end is pivotally attached to a collar 54 orother part fixed on and movable with the transverse shaft 4 and thesupporting arms 3. As the tension on the web passing into the pressincreases, the roller 38 is slidably moved in its guide 40 in adirection that causes the link 41 to move the bell crank lever 42against the action of the torsion spring 42a for raising the link 43 andimpart-112 ing angular movement to the shaft 45 and the pulley 46 withthe result that the cables 47 are slackened, thus enabling the brakeband 52 to be released to allow the active supply roll to rotate at ahigher speed. W hen the;

tension on the web decreases, the roller 38 slidably moves in its guide40 in the opposite direction due to the aforesaid torsion spring 42awith the result that the link and lover mechanism 41, 42 and 43 is movedin thef-i9 of the aforesaid arms 49 serves as a compenc eating devicefor taking up any slack in the cable 47 when the paper supply rollsupporting arms 3 are angularly moved,'by reason of the aforesaid link53 connected to the collar 54 which move with the said arms'3, angu- 0larly displaclng the'lever 49 so as to change the position of the jockeypulley 48 thus enabling the cable to be maintained taut for any angularposition of the said supporting arms link and lever mechanism 41, 42 and43 according to the tension on the web as herein before describedirrespective of the angular position of the supporting arms carrying wThe torsional effect of the paper supply roll. the spring 42a can bevaried according to requirements and for this purpose the worm wheel 55which is movable with the bell crank lever 42 and is connected to thesaid spring I vso that .they can be operated by the aforesaid i can berotated by the worm 56 whose spindle is provided with an operating handwheel 56a asshown in Figure 7. Each brake band 52 may be operated byhand if desired for which purpose a hand screw 57 may be mounted so asto be connected to the bell crank lever 51 (as shown in Figure 7 forenabling the latter to contract or release the brake band when the handscrew is rotated.
